RATLHOLDING-IDEVICE AND ANTICREEPER.

Application filed October 14, 1926 Serial N'o. 141,586.

This invention relates to rail fastenings and particularly to fastenings for prevent ing separation and creep between rail and tie.

NV hen the wheels of a railway train pass over the rails the action thereupon is 'to cause a depression in the rails immediately beneath the point of contact with the wheels, due to some extent to the compression of the rails, to some extent to the bending of the rails between the ties, but principally to the depression of the roadbed and accompanying sinking of the ties. The ties at :either side of the point of contact or point of load application have smaller unit loads and hencesinli less than the tie or ties nearest the point of load application. This being true, the edge of the tie toward the depression acts as a fulcrum for the railcausmg it to cant the tie or pull the spikes therefrom; and the tie as a whole acts as a fulcrum causing therail beyond it to lift, which raises the adjacent tie or pulls the spikes from it. The usual happening in both cases is the starting of the spikes which leaves;

the track in a dangerous condition for subsequent traftic.

- There is also a tendency of the rails to creep over the ties due to lengthening and shortening of the rails with changes of temperature, endwise push upon the railsby the driving wheels of locomotives, downgrade movement of the rails from gravitational forces coupled with the beat of wheels, and various other causes.

, it is, therefore, one object of .this invention to provide improved means for preventing separation of rail and tie. It is another object to provide improved means for preventing creep of therail over the tie. H A novel feature of this invention is the provision of asingle device for preventing both lifting and creeping of the rails. Another feature is the provision of such a device which is efficient in service, easy to apply, and inexpensive to manufacture.

Other objects and features of novelty will be apparent from the following description taken in connection with the drawings, in

which: I

device which is adapted to be used with a tie plate it) having flanges 11 along "the sides of a crosstie. A clip or fastening member l2 has lugs l5, 14: forming a jaw engaging a base flange of the rail, the upper lug-bemg' formed with a sloping under surface to fit I the top slope of the flangem The base or inner end of the is enlarged by undercutting the lugs as shown at 15 to permit 1 the aw to be wed ed u Jon the flan e. As

J b b shown in Figures and 5, the lug leis bent at an angle to the lowerlug or, taken in relation to the rail, thelug may 'be said to be bent at an acute angle to the axis of V I the rail or anangle to a plane perpendic alarm the rail.

The clip has a resilient tall or projection is of such dimensions and character as to oppose the lift of the rail. This appendage V .ongages a seat or abutment which is bent from the tie plate or otherwise suitably secured w th respect to the tie. The seat or abutment 17-slopes downwardly away from the rail. so that the projection 16 will wedge 'thereaga'inst upon upward movement.

A second projection 18 is formed on the; clip.

This projection is rigid and is disposed beneath a stop 19 rigidly secured to the'tie.

The stop is shown as being formed on the tie plate. The projection loniay fit directly against or lie a small distance below the stop 19. When'the left base flange of the rail as shown in Figure 1 tends to lift due to lifting or overturning the jaw grips it and j 1 carries the whole clip including the spring projection 16 upward. The projection 16 and stops the movement by spring action. If

tion 18 comes into contact with the stop 19 vto prevent further movement.

\Vhen the projection 18 engages the stop 19 in operation the clip acts as a lever turnthe movement is sufficient the rigid projecing about stop 19 and the projection 16' limits the movement in resilient fashion by flexing due to the engagement of its outer end with the seat 17. In case the projection 16 should break, the projection 18 will still engage stop 19 and act as a safety device.

The clip is secured to the tie by a gauge adjusting plate 20, bolt 21, and nut- 22. The bolt may pass through the tie plate and tie to hold the tie plate rigidly thereon or the bolt Inaypass through. the flange oi the tie plate only, in which case, the tie plate will be secured in any desired manner upon the tie.

The clip is curved or bent in the center in order that it may be lengthened by straightening to cause it to wedge between the seat or abutment 1"? and the flange of the rail. Straightening may be. accomplished either by pulling up the nut on bolt 21 or by hammering the clip before putting it into position.

' The action of the lip to prevent over turningor lifting or the rail has been explained. The clip not only serves this purpose but prevents longitudinal creeping of err-emu in one direction as well. Upon initial longitudinal movement oi the .rail against the out'bent end of the lug let of the clip, the lug will tend to straighten and Wedge tightly against the rail i'iange. Then since the clip isrigidly fastened to the tie, it will prevent creep between rail and tie. To stop creep inthe other direction it is only necessary touse a clip on the other side of the tie. in the drawings the second clip ispi'aeed diagonally opposite the first but it will be obvious that it the clips 2LIlCl,'tl18ll lugs are bent on the opposite side the clip may be used in either or both of the other "diagonally opposed positions.

' A modification oithis device is shown in Figures 4; and 5. Here a lug or stop 25 is disposed with its inner vertical edge a 'suihcient distance, from the base flange of the rail to permit the rail to seat upon a tie or if desired, 'upon -a tie plate as illustrated in Figures 4: and '5. The construction shown in Figure 5 is particularly adapted to be used in conjunction with poured concrete ties though obviously also adapted to be used with other types of ties. Here the lug or step has a shank 26 passing through the tie plate (it used) and into the tie. 1%. bolt 27 passes through the tie, preferably near the neutral axis to prevent undueweakening of the tie as a beam, and through a hole in the shank to hold the lug in position. The lug suitable tor use with the present modiiication may be struck up from the tie plate as shown in Figure 6 in connection with a further modification presently to be described. The lug has a curved notch 28 on one side and a curved edge 29 on the other side, both curves being struck from thesalne center.

A clip of springnretal is formed with an opening or slot 31 of proper size to closely lit against the curvedportion 29 01 the lug or stop 25 when the clip is in operative position. One end oi the clip is curved as 32 and fits between the-stop and the rail ilange; The cl p has a boss or Judge 33 iii-airing contact with the rail flange to prevent creeping oi the rail, clip being so tightly wedged 1n positlon upon the rail as to provide great friction resisting creeping of the rail. The reaction to creeping in either directionis taken by the lug since the clip straddles the lug.

To position the clip it is held with pro ye'ction 3% thereof in a nearly vertical po sition the slot 3l'passedover the step 25 the curved end 2-52 engaged in the curved notch'F JS and the clip iOtlt'GCtlll-lif) tl e position shown inl igure in this position Joint o'lycontact with the lu is be end the i in Joint of contact with the rail ilan e thus l a insuring that the iiexibleprejecticn rest upon the tie or'tie plate.

54 will This device is prererablyusedon the .-in-

side of the rail, any desired device being used to retain the rail on the outside,- such spikes or a ridge 35 on thetie plate as shown in Figure-d, though it may be used on either side of the rail with equal effective ness. K

Figure 6 shows another inodilication in which the lug or stop 36 has-a notch with an undercut seat 38, a spring clip. -39 has a slot l0longerthan the lug to allow the clip teb'e wedged into-position. The bent end 41 of the clip has a ridge d2 which snaps into position in the seat 88. A ridge or boss 43 on the main portion of the j clip serves the purpose of v preventing longitudinal creep as explained in connection with b'ossiiof lug is beyond the point of contact with the rail flange.

The outer end may likewise-be secured ir" desired to prevent unwarranted removal oi? the clip. V

in case a tie of "old rail of other metal is employed, lugs suitablei'or use with either the modification shown-in Figure 5 or that described with-Th me 6, may be struclr up from the flanges of the tie itself.

It is to be understood that the invention is not to be limited to the-embodiments illustrated, but may assume various other embodiments if within pended claims.

Having thus described the invention.
